the bad thing with football is that the coach just might want that extra weight to use him him as defense. its sick i know, but dont tell your son that, now i want to tell you a little about my eating habits and my weight.
i have a glass of milk for brekfast, lunch is some kind of sandwhich{blt, burger,pbj,and a drink} i snack on candy bars if i am busy cutting grass, or cleaning, to keep my sugar up, and to keep from getting sick feeling, no dinner, maybe once in a while i will make a staek with no sides, or stuffed chicken breast but no sides, just the chicken breast, but i eat all night long, soda, chips, whatever, but i do it in moderation, not a whole bag,
some days i eat junk non stop, for a while this winter, i ate a loaf of bread a day, whole milk, skittles i need rehab for skittles. the other day i pulled the cardboard off the ice cream and poured syrup on it and ate that for dinner. one night we had hot fudge brownie delights for dinner . i weigh 110, i had 2 kids, i DO not work out, but i also do not lay around on my but all day. i do not do diet pills or carbs or count calories.
1 thing on your plate for dinner is plenty, bbq chicken breast and a glass of milk is plenty, you dont have to have 3-4 things on your plate, think of it, 3 different foods at one, 3 times a day, thats 9 differt kinds of food, thats alot of food, and a lot of work cooking preparing,
if you worry about the food group thing, then one day have greenbean cassorole for lunch, or offer corn with dinner as it has no calories, just dont but a ton of food out 3 times a day and then wonder why "i keep gaining weight"
and dont be like my mother in law she thinks she can stuff her face all day as long as it says "low carbs" or "weight watchers"
with summer coming go swimming alot, or get him a gym set, with him wanting to play football, that would go over big time, if you cant afford one from the store, look in those ad weeklys, or yard sales, garage sales, see when he starts to works muscles, it will burn all the junk he eats and convert it into muscle, it wiil seem like he is putting on more weight at first, but muscle weighs more than fat, you will notice a difference real soon. he will eat more however, but as long as he works out every day that should be no problem, he will want lots of carbs, bread and pasta to help him build muscle,let him have it. as long as he works with his weights, tell him it will help him be a better football player{it will} the muscle he builds will help protect his bones and keep them from breaking while playing sports like football.
